Sperm motility parameters for Steindachneridion parahybae based on open-source software

Summary: The objective of this work was to evaluate the sperm motility of 13 Steindachneridion parahybae males using open-source software (ImageJ/CASA plugin). The sperm activation procedure and image capture were initiated after semen collection. Four experimental phases were defined from the videos captured of each male as follows: (i) standardization of a dialogue box generated by the CASA plugin within ImageJ; (ii) frame numbers used to perform the analysis; (iii) post-activation motility between 10 and 20 s with analysis at each 1 s; and (iv) post-activation motility between 10 and 50 s with analysis at each 10 s. The settings used in the CASA dialogue box were satisfactory, and the results were consistent. These analyses should be performed using 50 frames immediately after sperm activation because spermatozoa quickly lose their vigor. At 10 s post-activation, 89.1% motile sperm was observed with 107.2 μm s-1 curvilinear velocity, 83.6 μm s-1 average path velocity, 77.1 μm s-1 straight line velocity; 91.6% were of straightness and 77.1% of wobble. The CASA plugin within ImageJ can be applied in sperm analysis of the study species by using the established settings. © 2013 Blackwell Verlag GmbH.

Free tools and strategies for the generation of 3D finite element meshes: Modeling of the cardiac structures

The Finite Element Method is a well-known technique, being extensively applied in different areas. Studies using the Finite Element Method (FEM) are targeted to improve cardiac ablation procedures. For such simulations, the finite element meshes should consider the size and histological features of the target structures. However, it is possible to verify that some methods or tools used to generate meshes of human body structures are still limited, due to nondetailed models, nontrivial preprocessing, or mainly limitation in the use condition. In this paper, alternatives are demonstrated to solid modeling and automatic generation of highly refined tetrahedral meshes, with quality compatible with other studies focused on mesh generation. The innovations presented here are strategies to integrate Open Source Software (OSS). The chosen techniques and strategies are presented and discussed, considering cardiac structures as a first application context. © 2013 E. Pavarino et al.

Uma análise de aspectos relacionados ao desenvolvimento e adoção de Enterprise Resources Planning livre de código aberto

Sistemas Integrados de Gestão ou Enterprise Resources Planning - ERP possibilitam o processamento das informações necessárias em uma empresa usando um único banco de dados. Muito tem se escrito sobre este tipo de software, abordando questões como o alto custo da aquisição de licenças, e a dependência de consultoria para a sua adaptação e implantação nas empresas. Atualmente vem crescendo o desenvolvimento e uso de ERP Livre de Código Aberto (FOS-ERP). Porém verifica-se que este tipo de sistema ainda não é suficientemente explorado, mesmo no meio acadêmico. Este artigo relata alguns trabalhos publicados sobre o assunto e levanta questões que devem ser tratadas por pesquisadores e demais interessados para adequar e viabilizar o uso desses sistemas conforme a realidade nacional. Assim, após uma introdução ao tema, são apresentadas algumas diferenças entre o FOS-ERP e seus equivalentes proprietários (Proprietary ERP ou P-ERP) em termos de modelos de negócios, seleção, customização e evolução. em seguida são elencados alguns desafios e oportunidades que o FOS-ERP pode oferecer a usuários, fornecedores, pesquisadores e colaboradores individuais. Concluindo, este artigo busca ampliar a discussão sobre FOS-ERP, destacando fatores tais como seu potencial de inovação tecnológica e estratégias de negócios.

As possibilidades de uso de ferramentas da informática: software para análise de dados qualitativos e ISD

The objective of the present article is to identify and discuss the possibilities of using qualitative data analysis software in the framework of procedures proposed by SDI (socio-discursive interactionism), emphasizing free distribuited software or free versions of commercial software. A literature review of software for qualitative data analysis in the area of social sciences and humanities, focusing on language studies is presented. Some tools, such as: Wef-tQDA, MLCT, Yoshikoder and Tropes are examined with their respective features and functions. The software called Tropes is examined in more detail because of its particular relation with language and semantic analysis, as well as its embeded classification of linguistic elements such as, types of verbs, adjectives, modalizations, etc. Although trying to completely automate an SDI based analysis is not feasible, the programs appear to be powerful helpers in analyzing specific questions. Still, it seems important to be familiar with software options and use different applications in order to obtain a more diversified vision of the data. It is up to the researcher to be critical of the analysis provided by the machine.

Softwares livres e prototipagem rápida aplicados na engenharia

In modern industry we see a growing need for answers cheaper, accurate and quick to deliver solutions and products to be able to remain competitive. In this way the inclusion of open source software and Rapid Prototyping tools have proven very important to obtain the expected results. This work, through information gathering, analysis software and their applicability, search tools commercially available rapid prototyping will demonstrate the importance of these tools and will also present possible configurations for a space for rapid prototyping within the university, as a proposal to implement a rapid prototyping laboratory at the Faculdade de Engenharia de Guaratinguetá

Concepção e Implementação de um Sistema de Controle de Arborização Urbana através da Integração de Softwares Livres e de Código Aberto

Suitable computacional tools allow to build applications that can link information to its physical location, and represent them into visual and interactive schemes, e ectively reaching the power of visual comunication. This leads the user to synthesize information in a simple and e cient way. These applications are linked to the de nition of Geographic Information System (GIS). GIS are comprised by many concepts and tools, which have the main purpose of collecting, storing, viewing and processing spatial data, obtaining the information needed for decision making. Within this context, this paper presents the Conception and Implementation of a Control System for Urban Forestry through Integration of Free and Open Source Software. This conception arose from the need of an Environmental Project developed by the Agriculture's House of the city of Regente Feij o, which has as main objectives cataloging and management of urban a orestation of the municipality. Due to this diversity of concepts, the challenge in building this system is the integration of platforms that are involved in all stages: collecting and storage of data, including maps and other spatial information, operations on the stored information, obtaining results and graphical visualization of the same. After implementation, it was possible to provide for the system users an improvement in the capacity of perception in the information analysis and facilitate the process of decision making

Modeling architecture and reference models for the ERF5 project

The adoption of ERPs systems by small and middle-sized companies may not be possible due to their cost. At the same time, when adapting ERP to the company's particular needs, the user keeps depending on the system's sellers due to the lack of access and knowledge of the respective code. Free and open-source software may promote advantages to the enterprises, however, for its adoption it is necessary the development of techniques and tools in order to facilitate its deployment and code maintenance. This article emphasizes the importance of defining modeling architectures and reference models for the development and maintenance of open-source ERPs, in special the ERP5 project.
